A performance comparison investigation has been carried out for two multiple-weight, adaptive, canceler techniques; the discrete Fourier transform (DFT) band partitioning approach and the transversal filter canceler (TFC) approach. A simple two-channel canceler model was utilized, with all-digital processing, and four different types of channel error were included. For differential delay errors and amplitude/phase ripple errors, the TFC performance is generally far superior to the DFT subband system, for the same number of degrees of freedom. For quadrature errors and sample/hold jitter errors, there was essentially no difference in performance between the two, and performance did not improve as the degrees of freedom were increased. The superior performance of the TFC system is attributed to more effective utilization of its adaptive degrees of freedom and the fact that it is inherently suited to differential delay compensation. The DFT canceler has no differential delay compensation.
